Abstract

Fofana spaces, introduced in the framework of Wiener amalgam spaces, can be viewed as generalizations of Morrey spaces. These spaces have attracted considerable attention in recent years and have found applications in the study of partial differential equations. In this paper, we investigate their variable-exponent counterparts. More specifically, we describe Calderón's, first and second, complex interpolations of Fofana spaces with variable exponent, as well as the corresponding interpolation spaces of their preduals. Our results recover, as special cases, those already known for (classical) Fofana and Morrey spaces.

Löwner equations and de Branges--Rovnyak spaces

We study one-parameter families of de Branges--Rovnyak spaces associated with Löwner equations. The purpose of this paper is to give a new approach to a problem discussed by Sarason, Fricain--Hartmann--Ross, Fricain--Mashreghi, and Łanucha--Nowak. Our approach is based on a little-known technique, ``\textit{Löwner expansions}'', developed by the de Branges school. We recast ``\textit{Löwner expansions}'' in the theory of direct integrals and integral operators. Further, our framework also provides a natural setting for applying the theory of the chordal Löwner equation to the theory of de Branges--Rovnyak spaces. As an application, we prove Fourier-type expansion theorems induced by the Löwner equations.

On Continuous Wavelet Transform of Complex Radon Measures on $\mathbb{R}^{d}$

This paper investigates a necessary and sufficient condition for a measurable function on $\mathbb{R}^{\times} \times \mathbb{R}^{d}$ to be the continuous wavelet transform of a complex Radon measure on $\mathbb{R}^{d}$ under suitable regularity conditions on the wavelets. We investigate various integrability properties of the wavelet transform of complex Radon measures. We define a new norm on the collection of such functions and show that it is isometrically isomorphic to the Banach algebra of complex Radon measures under convolution. We show a wavelet inversion formula for measures, in a restricted sense. Under additional hypothesis, we provide a reconstruction formula for the measure of closed rectangles in $\mathbb{R}^d$ using wavelet transforms. We have included supporting examples to substantiate these assumptions.

Compressions of Linear Relations in Krein Spaces

Given an orthogonal decomposition \(\widetilde{\mathfrak{H}} = \mathfrak{H}[\dotplus]\widehat{\mathfrak{H}}\) of a Krein space, we study compressions \({\mathrm{C}_{\mathfrak H}}(R)\) of linear relations \(R\) in \(\widetilde{\mathfrak{H}}\) to \(\mathfrak{H}\). We formulate a sufficient condition that ensures that compression commutes with taking adjoints, that is, the adjoint identity \({\mathrm{C}_{\mathfrak H}}(R^{\widetilde{*}}) = {\mathrm{C}_{\mathfrak H}}(R)^{*}\) holds. We derive preservation and reflection results for the compression of maximal dissipative, maximal symmetric, and self-adjoint linear relations. For nonnegative linear relations, the adjoint identity also implies that compression commutes with taking the Friedrichs extension. For \(\mathfrak{H}\ne\{0\}\), we characterize finite dimensionality of the exit space \(\widehat{\mathfrak{H}}\) by universal compression properties. Finally, we give a criterion for the adjoint identity to hold in terms of bounded linear functionals on \(R\).
